Title

Magnet Bracelet Experiment

Problem Scenario

I am trying to see if magnets can effect your balance.

Broad Question

Do magnets help your balance?

Specific Question

What are the impacts of magnets on balance?

Hypothesis

If I took seventh graders and put magnet bracelets on half and put cardboard bracelets on the other half, then the seventh graders with the magnet bracelets will balance better.

Graph of Hypothesis

Variables

Independent Variable: the bracelets

Dependent Variable: the average balance of seventh graders

Variables That Need To Be Controlled: the bracelets that don't have the magnets

General Plan

First I am going to make magnet and cardboard bracelets. Then I am going to get

Experimental Design

(add the correct headings from the experimental design page before beginning)

Resources and Budget Table

Item	Number needed	Where I will get this	Cost
magnet tape	1 roll	Walmart	about 2.00
ribbon	1 roll	Walmart	about 3.00
duct tape	1 roll	Walmart	about 2.00
cardboard	not sure	house	free
7th graders	about 45	Team 3	free
timer	1	school	free
Display Board	1	Mr. Groves	5.00

Detailed Procedure

1. First you will need to make the magnet bracelets.
2. To make the magnet bracelets you will need magnet tape, yarn, and duct tape.
3. You use any length of yarn, as long as it can fit your wrist.
4. Then you have to take some magnet tape and wrap it around the yarn.
5. Next you take duct tape and cover up the magnet tape.
6. Make sure your magnet tape is still connected to the yarn.
7. If you need to, take some extra duct tape and tape the magnet to the yarn.
8. Now you are done with the magnet bracelets.
9. Do the same exact thing with the cardboard bracelets, except replace the magnet tape with cardboard.

Now you are ready to start the experiment.

1. To start the experiment you will need a group of people, a timer, and the bracelets.
2. Pick out a time you are going to do this experiment.
3. Now take four people at a time.
4. First you are going to need to put magnet bracelets on each one.
5. Then you have one person stand on one leg at a time.
6. Record how long they stood on one leg.
7. Do the same thing with the other people with the cardboard bracelts on.
8. Then take the times of how long the people stood on one leg and turn it into a graph.

Results

The first time when the kids balanced on one leg with the magnet bracelets 11 kids improved. The second time when the kids balanced on one leg without the magnet bracelets 3 kids improved.

Conclusion

In conclusion the magnet bracelets were a success. My hypothesis was correct. The first day I tested the kids I thought my magnet bracelets wouldn't work. But the magnet sports bracelets that people sell for about 40.00 can be made with magnets ribbon and duct tape. I was amazed on how many npeople improved. The second day I tested the kids I was pretty confident that this project was a success.

Benefit to Community and/or Science

The benefit to the community is that it helps save money because you can make the bracelets at home for only about 5.00 or maybe free. This experiment also helps science because
